IMPROVEMENT IN PRIMING; METALLIC' CARTRIDGES.

Speezlficalionfarming part of Letters PatentN 62,467, dated February 26, 1867.

To all whom it may concern Be it known that I, ALEXANDER J. BERGEN, ofBi-ooklyn, in the county of Kings and State of' New York, have invented, made, and applied to use a certain new and usei'ul Improvement in Cartridges; and l do hereby declaro the following to be a full, clear, and exact description of my said invention, reference being had to the annexed drawing, making part of this specification, wh erein Figure 1 is a longitudinal section of a. shotcartridge itted with'i my improvement. Fig. 2 is a section of the metallic case; and Fig. 3 is a detached section ot' the fulminatc-nipplc.

Similar marks denote the same parts.

Cartridges have heretofore been made with the tube containing the`t'ulminate, and they have also been made with a central cavity or hole to receive a cap that is exploded by a blow upon the central rear end ofthe cartridge. A. central teat has also been employed, projecting from the rear end of the cartridge, as

seen in Letters Patent granted January 5, 1864, No. 41,184.

The nature of my said invention consists in a movable fulminate'nipple projecting from the rear end of and in combination with a cartridgecase formed with a cavity in the rear end into which said fulminate-nipple is inserted. Ry this construction the explosion iseft'ected by a blow on the side of the projecting nipple, and the flash is directed into the cartridge upon the central portion of the powder, and the iiame cannot escape because the pressure of the gases tends to make the nipple tighter within the cavity of the case, and the case itself can be used several times by intro ducing the usual powder and ball or shot and inserting a new fulminate-nipple.

In thedrawing, a is the cartridge-case, formed with either a iiat or dome-shaped base, I), and with the flange, e, as seen in Fig. 1, or without it, as seen in Fig. 2. and said cartridge is to be adapted to any desired size or character of fire-arm and to the reception of a ball or of shot or slugs.

ois a central cavity pressed into the base of the cartridge-case, and havingl a small opening for the iiame from the detonating material to reach the powder.

t' is the fnlminatenipple, of a size to set tightly within the cavity o, and of a length to project suticiently to allow oi' the hammer striking the side oi' the nipple and exploding the fulminate.

By this construction the cartridge-case docs not receive any strain or concussion from the hammer, and `hence does not require to be ot` heavy metal.

v What I claim, and desire to secure by Letters Patent, is

A movable fulminate nipple, projecting from the rear end of and in combination with a cartridge-case, formed with a cavity in the rear end for the reception ot' said nipple, substantially as set forth.

In witness whereof I have hereunto set my signature this 23d day of October, A. D. 1866.

A. J. BERGEN.
